Isaac Clarke in Dead Space 2. It would take a long, depressing explanation of my personal life to properly explain why, so to make a long story short, I can relate to a lot of what he's going through with Nicole because it reminds me of what I went through when my mom died. That combined with the fact that he's just an all-around awesome dude means I care about him a lot. Playing Dead Space 2 felt like I was literally battling my own bottled up grief through that character, and as a result, it's probably the one game that's had the most powerful emotional impact on me.
